make index.html use the base template
first WIP pass at selenium testing
 my goal here is to eventually make this get through the attendee-facing preregistration process
 if I can do that, I will sleep a lot better at night having these tests run against production and staging servers
 this obviously needs a ton of work to be useful, but it is a decent start
 I'm probably getting too goofy with my static methods and globals, but we can clean it up later if this sticks.
